在我的應用程序中,我試圖讓用戶能夠看到他們的帖子。現在,用戶只能看到他們最近的帖子,出於某種原因,並非所有的帖子都會經過並被添加到「myPosts」數組中。當我打印一個字典的「postDict」時,它給了我所有用戶所做的帖子的正確值,但出於某種原因,數據沒有通過並被添加到數組中。請幫助並參考代碼和我的JSON樹中的註釋。Xcode swift table view只顯示一個數據值而不是全部
import UIKit
import Firebase
class MockPostVC: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var tableView: UITableView!
var mockPost: MockPost!
var myposts = [MockPost]()
var postKey: String?
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.delegate = self
self.tableView.dataSource = self
DataSevice.ds.REF_USER_CURRENT.child("posts").observeEventType(.Value, withBlock: { snapshot in
if let snapshots = snapshot.children.allObjects as? [FIRDataSnapshot] {
for snap in snapshots{
var y = "\(snap)"
var x = y.componentsSeparatedByString("Snap (")
var z = x[1].componentsSeparatedByString(") 1")
DataSevice.ds.REF_POSTS.observeEventType(.Value, withBlock: { snapshot in
self.myposts = []
if let snapshots = snapshot.children.allObjects as? [FIRDataSnapshot] {
for snap in snapshots{
if "\(z[0])" != snap.key{
}
else{
if let postDict = snap.value as! Dictionary<String, AnyObject>?{
self.postKey = snap.key
let mockPost = MockPost(dictionary: postDict, postKey: snap.key)
self.myposts.append(mockPost)
//self.myposts.count returns as 1
//for some reason only the first post is getting registered into the array
}
}
}
}
self.tableView.reloadData()
})
